SPECIFICATION forming part of Letters Patent No. '713,803,`datedNovember 18, 1902.

Application filed .Tune 30,1902.

To all whom it may concern,.-

Be it known that I, Josnr ROTHWEILER, a citizen of the United States,and a resident of Chicago, Cook county, State of Illinois, have inventedcertain new and useful Improvements in Insect-Traps; and my preferredmanner of carrying out the invention is set forth in the following full,clear, and exact description, terminating with claims particularlyspecifying the novelty.

This invention relates to traps, and more especially to that classthereof which are adapted and intended to catch insects, such as roachesor others which crawl.

The object of the invention is to improve the construction of devices ofthis character, to which end it consists in the details hereinafterpointed out.

The invention is more fully described in the following specification,pointed out the claims, and shown in the drawings, where- 1n- Figure Iis a central longitudinal sectional View of this trap, and Fig. II is aplan View of the same.

Referring to the drawings, the numeral 3 designates the body intended tobe about half lled With Water to the water-line 30. rlhis body is ofclay or similar materiahglazed on its interior and rough on itsexterior, as at 1. It has a flat bottom and slightly conical side walls,and by reason of its rough exterior the insects can crawl upward overthe same. In shape this body is circular, as seen in Fig. II, and at thetop of its side Wallis a downwardlyprojecting flange 2, which is glazedor smooth on its upper surface, whereby when the insects have crawled upthe exterior 1 and over onto the flange 2 they slip down the latter intothe water and are trapped.

The numeral 40 designates a pillar or post preferably molded integralwith the bottom and rising therefrom at the center thereof, and at thetop of this post is formed a cup 4, in which food is placed, so as toconstitute the bait to attract the insects. The periph- Serlal No.113,814. (No model.)

ery of this food-cu p is sufficiently remote from the upper edge of thetop to prevent the insects from doing more than reach toward it, andthis prevents consumption of bait.

The water is poured into the device in a manner which will be clear, andit is poured out of it through a notch 5,formed at one point in the ange2 for this purpose. If it were not for this notch,the water wouldbe-trapped in the interior and could not all be poured out.

As before stated, the device is preferably molded from clay or potteryof suitable thickness and preferable dimension, the important featuresbeing that it shall be rough on the exterior of the body and smooth onthe interior of the flange, and also that there shall be a notch in thelatter to permit the pouring out of the Water.

What is claimed as new is 1. An insect-trap consisting of a cup-shapedreceptacle having conical side Walls which are rough on their exterior,and an inwardly-projecting flange at the upper end of said walls andsmooth on its interior; combined with a centrally-disposedbait-receptacle,and a notch in said iiange at one side, for the purposeset forth.

2. An insect-trap consisting of a circular cup-shaped receptacle having`conical side Walls, and an inwardly-projecting flange at the upper endof said Walls the flange having a notch at one side; combined with apillar rising from the base of said receptacle and having a cup at itsupper end for bait, the walls of the cup being farther removed from theinnermost edge of the flange than the distance which the ordinary insectcan reach, as and for the purpose set forth.

In testimony whereof I have hereunto subscribed my signature this the23d day of June, A. D. 1902.
